Right now if you edit a post during the grace period the following will happen:
- The post is silently changed without any notice (such as "last edited 1 min ago")
- The added/removed/changed text is not available in the revision history (there is no revision entry at all)
- The question is not bumped to the top of the activity page
- The edit doesn't count towards the auto-CW limit and is ineligible for certain badges (such as Strunk & White).
Now, the last 2 points are totally fine but the first two cause a great deal of confusion to both experienced and new users.
I propose that every edit made in the grace period adds a new revision and triggers the "last edited" notification on the post body, while not bumping the question or count towards the CW limit.
This has several advantages:
- It follows the principle of least astonishment. The observable behavior of every edit is the same.
- It allows us to read past revisions (for curiosity or other reasons)
- In general, it will cause much less confusion
In fact, I don't really see any advantage of the current approach.. Maybe less cluttering on the revision page? Does it really matter? I don't think so
